bebe, baby, sweetie, lovey, darling, sugar babe, it’s not about male or female .. it’s about choosing a cute and personalized name to call your gf or bf. something you don’t hear others use very often. something you both like... calling him master or commander may not work best. it’s not about masculine vs feminine but more about using one name that your close friends don’t use usually so as to differenciate between all the different babys and honeys out there.. it’s not brain science..( you can call me Commander, or Commandante :)
